3MM CS X 9MM ID BLACK FKM 75D

V3X9 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 9 mm (0.354 in), a cross section of 3 mm (0.118 in), and an outside diameter of 15 mm (0.59 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Viton® (FKM) is known for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. This material stands up to chlorinated solvents, aromatic hydrocarbons, and aggressive chemicals. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

It sees regular use in chemical processing, high-temperature process equipment, and automotive fuel systems.
